quick and dirty icon theme viewer

So very often I find myself trying to find the name of an icon in the icon theme, and I end up having to search through my icon theme with a combination of find and eog. Usually I miss the icon on my first pass through.

Today I cracked, and decided to hammer together a quick and dirty viewer and searcher for the icon theme which looks something like this:

icon theme viewer
It's written in PyGTK and so far only has the single feature of 'Search' (this is my 90% case). It could be a lot more advanced if people wanted to hack on it: it could select themes, show whether an icon is in this theme or a parent theme, what sizes are available, etc. I will certainly accept patches!

Hopefully other people find this useful too. Source code is here.
